We analyze the effect of investor attention on stock prices around Chapter 11 bankruptcy filings. We measure investor attention as abnormal search volume from Google, and find that attention‐grabbing companies have more negative abnormal stock returns in the days before and during bankruptcy filings and more positive abnormal returns immediately thereafter. That is, for companies receiving high attention, investors overreact to a bankruptcy filing; for companies receiving low attention, they underreact. This pattern is more pronounced for companies with low institutional ownership and holds after controlling for standard predictors of stock performance during bankruptcy.  相似文献

This study examines stock market reactions to public announcements (corporate bond rating changes), including changes in stock prices and investor behavior in terms of trading volumes and patterns. Abnormal returns, abnormal volumes, and net order imbalances are estimated using high-quality stock transaction data from Korean firms, whose bonds were rated by Korea's leading credit rating agencies between 2000 and 2015. We find positive (negative) abnormal stock returns around upgrades (downgrades), although the stock price reactions to downgrades are more statistically significant than those to upgrades. Significant abnormal volumes and order imbalances are found around rating changes, and the extent to which each investor group (domestic individuals, domestic institutions, or foreign investors) reacts to a rating change varies. Our analyses also support that foreign and domestic institutional investors are better informed than individual investors.  相似文献

This paper documents a strengthening in the lead of stock index futures returns over stock index returns around macroeconomic information releases. Some evidence of a strengthening in feedback from the equities market to the futures market and weakening in the lead of the futures market around major stock‐specific information releases is also provided. This is consistent with the hypothesis that investors with better marketwide information prefer to trade in stock index futures while investors with stock‐specific information prefer to trade in underlying stocks. A small weakening in the contemporaneous relationship between stock index futures returns and stock index returns around both types of releases is also documented. This is consistent with disintegration in the relationship between the two markets associated with noise induced volatility. One by‐product of this study is new comparative evidence on the performance of adjustments for infrequent trading of index stocks based on a commonly used ARMA technique versus recalculation of the stock index using quote midpoints. The results suggest that the quote midpoint index performs at least as well as the ARMA adjusted index across the entire sample period, as well as around the different types of information releases. © 2000 John Wiley & Sons, Inc.

With the large expansion of Islamic finance in the recent years, sukuk , which are the Sharia‐compliant substitute to conventional bonds, are now becoming more prominent. The aim of this study was to examine the impact of sukuk issuance on firm performance. To do so, we analyse how stock market performance and operating performance (OP) are influenced by issuance of sukuk and bonds on a sample of Malaysian listed companies. We consider the short‐term and medium‐term stock market reaction through the computation of cumulative abnormal returns and buy‐and‐hold abnormal returns. We investigate the impact on OP by performing regressions and by calculating abnormal operating performance (AOP) so that we can compare how issuance affects similar firms. We find that sukuk issuance generates a negative stock market reaction both in the short term and in the medium term. We also find evidence that issuing sukuk hampers OP. The analysis of AOP shows that sukuk issuers have better performance than their matched bond issuers, but that sukuk contributes to reduce the gap in performance over time. Overall, our results support the view that sukuk issuance hampers stock market performance, but that it is not attributable to a signalling effect on the bad financial situation of the issuer. We interpret our findings as evidence of adverse selection taking place on the financed projects and agency problems stemming from the specific sukuk structuring with stock market investors more reluctant to invest in sukuk issuers.  相似文献

The risk–return relationship is one of the fundamental concepts in finance that is most important to investors and portfolio managers. Finance theory argues that the beta or systematic risk is the only relevant risk measure for investors. However, many studies have showed that betas and returns are not related empirically, no matter in domestic markets or in international stock markets. This paper examines the conditional relationship between beta and returns in international stock markets for the period from January 1991 to December 2000. After recognizing the fact that while expected returns are always positive, realized returns could be positive or negative, we find a significant positive relationship between beta and returns in up market periods (positive market excess returns) but a significant negative relationship in down market periods (negative market excess returns). The results are robust for both monthly and weekly returns and for two different proxies of the world market portfolio. Our findings indicate that beta is still a useful risk measure for portfolio managers in making optimal investment decisions.  相似文献

We examine whether military regimes harm stock market performance by investigating stock returns in ten emerging markets under military and civilian rule. We find no evidence of military regimes having a significantly negative impact on stock returns. In the case of Thailand and Pakistan, we find a significant positive military return premium. These returns cannot be explained by economic cycles, stock market cycles, or returns volatility. Our findings are robust to worldwide stock market movements, tests for spurious regression bias and randomization-bootstrap tests. Our results contradict the common view that military rule has a negative impact on stock market performance.  相似文献

The article examines the relationship between daily returns of currency carry trades and U.S. stocks from January 1995 through September 2010. Carry trade and stock returns are highly correlated with no Granger‐causality in either direction. An EGARCH model shows that significant volatility spillovers flow from the stock market to the carry‐trade market, but not vice versa. The markets are more correlated in periods of high volatility. Volatilities in both markets also increase more with negative innovations than positive innovations. A sectoral analysis of the index suggests that volatilities of cyclical stocks have more impact than noncyclical stocks on carry trades.  相似文献

We report on a seasonal pattern that has persisted in the Japanese stock market for more than half a century: Mean stock returns are significantly positive for months during the first half of the calendar year and significantly negative for months during the second half. Dubbed the Dekansho‐bushi effect, this seasonality is independent of other known calendar anomalies, such as the so‐called January effect. The Dekansho‐bushi effect should be distinguished from the ‘sell in May effect,’ because Japanese stocks perform well in June and poorly in November and December. The Dekansho‐bushi effect varies in magnitude among firms and is particularly significant among small firms with high book‐to‐market ratios. Nonetheless, the effect exists, regardless of a company's size or book‐to‐market ratio.  相似文献

This paper investigates the impact of retail attention on stock price crash risk in the Chinese stock market. Developing a composite measure of retail attention emphasizing its dynamic changes, we find that retail attention exacerbates future crash risk, which is robust to numerous checks that accommodate possibly omitted variables, apply the fixed effects model and instrumental variable approach, and adopt a legal interpretation as an exogenous policy shock. Extended analyses show that the impact of retail attention is more pronounced for firms with high information uncertainty under optimistic aggregate states. Moreover, using a sample of attention-grabbing stocks, we find that retail trades offer a crucial linkage from retail attention to crash risk. Overall, our findings are helpful to understand the nature of retail attention and its consequences on trading behavior as well as stock returns.  相似文献

Some thirty million American consumers pursue their financial objectives through individual participation in the stock market. They clearly view the stock market as a savings alternative which offers at least normal returns to persons outside the circle of professional investors. In the absence of data reflecting the performance of personal portfolios it is difficult to assess the validity of this view. However, as an initial step this paper evaluates the performance of the market servicing individual investors. The evidence indicates that noninstitutional investors have reason to question stock brokerage pricing, service and sales practices. Moreover on the basis of more than 1,000 sampled investment recommendations, it appears that investment publications directed at individual investors have failed to identify superior investment alternatives.  相似文献

Recent studies show that firms with higher analysts’ earnings forecasts dispersion subsequently have lower returns than firms with lower forecasts dispersion. This paper evaluates alternative explanations for the dispersion–return relation using a stochastic dominance approach. We aim to discriminate between the hypothesis that some asset pricing models can explain the puzzling negative relation between dispersion and stock returns, and the alternative hypothesis that the dispersion effect is mainly driven by investor irrationality and thus is an evidence of a failure of efficient markets. We find that low dispersion stocks dominate high dispersion stocks by second‐ and third‐order stochastic dominance over the period from 1976 to 2012. Our results imply that any investor who is risk‐averse and prefers positive skewness would unambiguously prefer low dispersion stocks to high dispersion stocks. We conclude that the dispersion effect is more likely evidence of market inefficiency, rather than a result of omitted risk factors.  相似文献

We use a nonparametric causality‐in‐quantile test to analyze the predictive ability of the wealth‐to‐income ratio (wy) for excess stock returns and their volatility. Our results reveal that the wy is nonlinearly related with excess stock returns, and hence, results from linear Granger causality tests cannot be deemed robust. When we apply the nonparametric causality‐in‐quantile test, we find that the wy can predict excess stock returns over the majority of the conditional distribution, with the exception being the extreme ends, that is, when the market is in deep bear or bull phases. However, the wy has no predictability for the volatility of excess stock returns.  相似文献

This study examines abnormal stock market returns of new listings on the Tunisian Stock Exchange. Substantial positive abnormal returns are found on the first listing day and this finding is similar to that obtained in other countries. Subsequent performance is poor and investors who bought shares at the close of trading on the first day would have lost about 22% against the Tunis Stock Exchange index over a three–year period. The possible causes of this are investigated. Among the factors found in the literature that possibly affect the level of long–term performance, only the state of the IPO market, the initial return, the delay in reaching the ‘first market price’ and the size of the firms have significant coefficients. This result is supportive of the traditional fad’s interpretation of long–term underperformance.  相似文献

中国股票市场行为与投资者情绪   总被引:1,自引:0,他引:1  
The relationship among stock returns, market volatilities and individual investor sentiment is an important topic in behavioral economics and finance. This paper uses a unique data set—China’s newly opened stock trading accounts to test the relationships among stock returns, volatilities and individual investor sentiment in the Chinese stock market. It is found that there is a positive relationship between shifts in sentiment and stock returns, and that shifts in sentiment are negatively correlated with market volatility, that is to say, volatility increases (decreases) when investors become more bearish (bullish).   相似文献

The study revisits the stock–oil nexus by examining the reactions of equity markets to oil price shocks at national and sectoral levels for Saudi Arabia in a time‐varying framework by employing the Markov switching EGARCH model developed by Henry (2009, Journal of Banking and Finance, 33, 405). Based on weekly data, the findings reveal that the behaviour of all stock markets switches between an expansion regime and a recession regime, with more persistence for the expansion state. Additionally, influential international events associated with stock market drops are clearly identified in the recession regime. Furthermore, there is evidence of asymmetric reactions of the equity index returns and the probabilities of transition from one state to another to oil price variations, with heterogeneous impacts across sectors and regimes. The stock markets are more sensitive to oil price decreases than to oil price increases. Although the evidence of relatively slight differences in some findings across weekdays, the study allows investors and policymakers to understand well the interactions of stock sector markets vis‐à‐vis the world oil market in a regime‐switching framework, in order to make the right decision as regards portfolio diversification and regulation of the stock markets.  相似文献

We investigate the size and value factors in the cross‐section of returns for the Chinese stock market. We find a significant size effect but no robust value effect. A zero‐cost small‐minus‐big (SMB) portfolio earns an average premium of 0.61% per month, which is statistically significant with a t‐value of 2.89 and economically important. In contrast, neither the market portfolio nor the zero‐cost high‐minus‐low (HML) portfolio has average premiums that are statistically different from zero. In both time‐series regressions and Fama–MacBeth cross‐sectional tests, SMB represents the strongest factor in explaining the cross‐section of Chinese stock returns. Our results contradict several existing studies which document a value effect. We show that this difference comes from the extreme values in a few months in the early years of the market with a small number of stocks and high volatility. Their impact becomes insignificant with a longer sample and proper volatility adjustment.  相似文献

We use quantile regression to investigate the short‐term return‐volatility relation between stock index returns and changes in implied volatility index. Neither the leverage hypothesis nor the volatility feedback hypothesis effectively explains the asymmetric return‐volatility relation. Instead, behavioral explanations, such as the affect and representativeness heuristics, are supported by our results, particularly in the short‐term; the affect heuristic plays an important role. Moreover, in the context of an extreme volatility change distribution, the affect heuristic and time‐pressure dominate. Thus, we observe strong negative and asymmetric relations between each volatility index and its corresponding stock market index. The asymmetry increases monotonically from the median quantile to the uppermost quantile (i.e., 95%); therefore, ordinary least squares (OLS) regression underestimates this relation at upper quantiles. Additionally, the VIX presents the highest asymmetric return‐volatility relation, followed by the VSTOXX, VDAX, and VXN. Finally, the observed asymmetry is more pronounced with the new volatility index measure than with the old, at‐the‐money volatility index measure. © 2012 Wiley Periodicals, Inc.

Antitrust enforcement of supermarket merger activity during the late 1980s and early 1990s was less stringent than it had been before or has been since. For six announcements of supermarket acquisitions during this period, this study examines the abnormal stock returns of rival firms to determine if investors believed these acquisitions would lead to higher retail prices.These abnormal returns imply that investors expected that the average retail price change associated with these types of acquisitions ranges from a 0.12% decrease to a 0.05% increase. Thus, our results suggest that investors generally did not view these acquisitions as anticompetitive.  相似文献

Arbitragers’ activities are constrained by market liquidity. In turn, arbitrage activity may trigger order imbalances adversely affecting liquidity. We examine this issue by analyzing the link between the futures‐cash basis and bid–ask spreads using intraday data on single stock futures (SSFs) contracts on Indian stocks. In contrast to other countries, the SSF market in India is very active due to retail investors’ prior experience with the badla system, a form of forward markets. The analysis reveals two‐way Granger causality between the basis and spreads in both the futures and cash markets. Evidence for spreads Granger‐causing basis is stronger for stocks with higher volume and SSFs that are relatively more active than underlying stocks. © 2012 Wiley Periodicals, Inc.

This article examines the risk and return profiles of stock indices composed of companies meeting environmental, social and governance (ESG) screening criteria [such as the Dow Jones Sustainability Indices (DJSI)] and conventional composite indices of eight Asian countries from 2002 to 2014. The results indicate that there are no significant differences in the returns or risk‐adjusted returns between the ESG indices and the composite indices within countries. The results do reveal that the market volatility of the ESG indices is higher than the market volatility of the conventional indices. Market betas of DJSI and ESG equity indices are significantly lower than betas of the composite equity indices. The overall results indicate that the performance of ESG equity indices of many Asian countries is similar to the performance of conventional indices, suggesting that investors can pursue socially responsible investing objectives without a material difference in portfolio performance from conventional investing.  相似文献
